Abstract

The utility model relates to a sucker rod pump, in particular to a tubular oil well pump used for medium deep well. The technical proposal of the utility model is that: the oil well pump mainly comprises a pump barrel coupling, a pump barrel, a plunger, an oil drain device, a fixed valve and a short piece, wherein, the pump barrel is directly arranged on the lower end of the pump barrel coupling; the fixed valve is arranged on the lower side of the pump barrel; a pumping rod is arranged on an inner cavity of the pump barrel and connected to the upper side of the plunger which is arranged on the upper side of the fixed valve; the oil drain device is arranged between the plunger and the fixed valve. The utility model has the advantages of improvement of the service life of the pump, simple structure, high reliability, and convenient operation, and the requirements of different customers can be met to produce oil well pumps with different strokes and clearances.

Description

Tubing pump
One, technical field:
The utility model relates to a kind of bar oil production equipment that has, particularly a kind of tubing pump that is used for middle-deep well.
Two, background technique:
Tubing pump is used widely in the mechanical oil recovery in oil field, and it is a kind ofly to be used for that middle-deep well is comparatively ideal the bar oil production equipment, but the problem that existing tubing pump exists is that working life of pump is shorter, and reliability is not high, has wasted ample resources.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provide a kind of simple in structure, reliability is high, the tubing pump of long service life.
Its technological scheme is: mainly be made up of pump barrel box cupling, pump barrel, plunger, oil drainer, standing valve and pipe nipple, pump barrel is directly installed on the lower end of pump barrel box cupling, and standing valve is contained in the below of pump barrel; And at the inner chamber of pump barrel, connect sucker rod on the plunger, and be arranged at standing valve above, be provided with oil drainer between plunger and the standing valve.
The beneficial effects of the utility model are: improved the working life of pump, simple in structure, reliability is high, easy to operate, and can satisfy the different strokes that the different user requirement makes and the oil well pump in gap.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, embodiment:
In conjunction with the accompanying drawings, the utility model will be further described:
Mainly be made up of pump barrel box cupling 1, pump barrel 3, plunger 2, oil drainer 5, standing valve 4 and pipe nipple 6, pump barrel 3 is directly installed on the lower end of pump barrel box cupling 1, and standing valve 4 is contained in the below of pump barrel 3; And at the inner chamber of pump barrel 3, connect sucker rod on the plunger 2, and be arranged at standing valve 4 above, be provided with oil drainer 5 between plunger 2 and the standing valve 4.
Working principle: during the pumping unit motion, drive sucker rod and plunger straight line motion up and down reciprocatingly, pump.When plunger began the up-down stroke operation, under the effect of fluid column gravity, the pump barrel internal pressure of plunger below reduced in oil pipe, and under the effect of oil pressure, standing valve is opened in the sleeve pipe toroidal cavity, and fluid enters by in the up cavity that causes of plunger.When plunger began down stroke, standing valve cut out, and plunger below pump barrel internal pressure increases, thereby when the plunger upstroke, well liquid enters in the toroidal cavity of the sucker rod of plunger top and oil pipe.When next upstroke, these well liquid and sucker rod in the oil pipe toroidal cavity remaining well liquid by on carry.
